Local & Post Notification
1) First Set Your Storyboard Like This :
2) Write Coding Which Is Given Below :
*ToDoListViewController (Set Notification) :
ToDoListViewController.h :
#import <UIKit/UIKit.h>
@interface ToDoListViewController : UITableViewController
@end
ToDoListViewController.m :
#import "ToDoListViewController.h"
@interface ToDoListViewController ()
- (void)reloadTable;
@end
@implementation ToDoListViewController
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(reloadTable)
name:@"reloadData"
object:nil];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [[[UIApplication sharedApplication] scheduledLocalNotifications] count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
// Get list of local notifications
NSArray *localNotifications = [[UIApplication sharedApplication] scheduledLocalNotifications];
UILocalNotification *localNotification = [localNotifications objectAtIndex:indexPath.row];
// Display notification info
[cell.textLabel setText:localNotification.alertBody];
[cell.detailTextLabel setText:[localNotification.fireDate description]];
return cell;
}
- (void)reloadTable
{
[self.tableView reloadData];
}
*AddToDoViewController (Show In tableView & Fire) :
AddToDoViewController.h :
#import <UIKit/UIKit.h>
@interface AddToDoViewController : UIViewController <UITextFieldDelegate>
- (IBAction)cancel:(id)sender;
- (IBAction)save:(id)sender;
@property (weak, nonatomic) IBOutlet UITextField *itemText;
@property (weak, nonatomic) IBOutlet UIDatePicker *datePicker;
@end
AddToDoViewController.m :
#import "AddToDoViewController.h"
@interface AddToDoViewController ()
@end
@implementation AddToDoViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.itemText.delegate = self;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)cancel:(id)sender
{
[self dismissViewControllerAnimated:YES completion:nil];
}
- (IBAction)save:(id)sender
{
[self.itemText resignFirstResponder];
// Get the current date
NSDate *pickerDate = [self.datePicker date];
// Schedule the notification
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = pickerDate;
localNotification.alertBody = self.itemText.text;
localNotification.alertAction = @"Show me the item";
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
// Request to reload table view data
[[NSNotificationCenter defaultCenter] postNotificationName:@"reloadData" object:self];
// Dismiss the view controller
[self dismissViewControllerAnimated:YES completion:nil];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[self.itemText resignFirstResponder];
return NO;
}
@end
